CASH AND PARCEL CARRIER.

.SPECIFIGATION forming part of Letters Patent No. 309,505, dated December 16, 1884.

Application filed November 22, 1884. (No model.)

To (tZZ whom it may concern:

Be it known that we, MILTON CLARK, of

New York, in the county of New York and State .of New York, and JAMES 'I. COWLEY, of Baltimore, in the county of Baltimore and State of Maryland, have invented certain new and useful Improvements in Cash and Parcel Carriers; and we do hereby declare that the following is a full, clear, and exact description of the invention, which will enable othit appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification.

' Our invention relates to that class of wheeled carriers in which the wheel or wheels are above the track and the frame of the carrier extends past one side only of the track, as shown in the accompanyin drawings, in which- Figure l is a side view of acomrnon form of carrier, showing that side along which the frame A extends below track 10. Fig. 2 is a view of the other side of this carrier, showing our invention, the yielding gatef. Fig. 3 is a section on line 00 00, Fig. 2; Fig. 4., a section on line yy. Fig. 2; Fig. 5, a section on line 2 2, Fig. 2. Fig. 6 is an inverted perspective detail of the arms and gates.

It has long been common to extend a part of the frame marked a under the groove of the wheel; but where the track is supported by a bracket or arm, to, an opening must be left between the wheel and the frame, as shown in Fig. 4:, which is a crosssection of our carrier, showing this opening as occupied by the bracket or arm marked 20', which supports the track w.

It will be clear from the drawings that that part of the frame A marked a and that part of the frame marked a will together make it impossible for the car to leave track to except by means of the opening between the wheel D and that part of the frame marked a; and it will also be clear that there must be such an opening when the carrier is to be used on a track, w, supported by brackets or arms 10.

In practice, especially when a wire track is used, it occasionally happens that a car falls from the track even when this opening is made as small as it can be made practically. We have therefore invented the yielding gate f, shown on the left of Fig. 2 and in Figs. 8, 4 as closed, and on the right of Fig. 2 and in Fig. :1: as open. I

Fig. 3 shows that when gatef is closed the track 20 is surrounded by the frame A, gate f, and periphery of wheel D, just as if gatef were in one piece with frame A; and Figs. 2 and 4 show clearly the operation of the gate when the carrier passes bracket 10.

It will be obvious that the gatef may be largely varied in form, and we have tested many forms, but on the whole prefer that form shown in the drawings for two-wheel carriers on a wire track. The guard-piece a", while not essential, is yet desirable,as itserves as a convenient stop for the gates. It is held to the frame A by the stud a Gravity may be used instead of a spring to return the gate to place after the carrier has passed bracket 10, and a single gate, f, willanswer well instead of two gates, as shown in the drawings. WVhen but one gate is used with a two-wheeled carrier, we have found it better to arrange it nearly midway between the wheels; but when two gates are used, as in the drawings, it is better to arrange one near each wheel.

\Ve have shown the gate as journaled on a stud fast to a part of the frame below the track w, but it may obviously slide on ways or be attached to a part of the frame above the track 20; but in the latter case the gate will be raised by contact with bracket to instead of being lowered, as shown in the drawings, for it is clear that our invention does not relate to the details of construction, but consists in a 0 movable piece, j, which yields readily whenit is brought in contact with bracket to by the motion of the carrier and returns to place at ter the carrier passes by bracket w.

hat we claim as our invention is- 5 1. A yielding gate, in combination withthc wheel and frame of the carrier, substantially as described.

2. The combination, with the car body partly surrounding the under periphery of the wheels,whereby a space is formed to pereach end, whereby said gates are prevented mit passage of the track, of the gates f and from having too great an upward and inward their connecting-spring, substantially as cle movement, substantially as described;

scribed.

3. The combination, with the car body or frame, of the guard, the gates f, and their connecting-spring, substantially as described.

4. The combination, with the car-body constructed as described, of the gates f, having a shoulder, their connecting-spring and the guard having a shoulder or stop formed at our own we aflix our signatures in presence of two witnesses.
